Dear all, I've built binary distributions for Mac OS 10.4 (Tiger) based on (better supported) GMP and GNUreadline frameworks and for Solaris 10. http://www.dfki.de/sks/hets/mac/versions/ghc-6.8.2-powerpc-apple-darwin.tar.... http://www.dfki.de/sks/hets/intel-mac/versions/ghc-6.8.2-i386-apple-darwin.t... The frameworks under http://www.haskell.org/ghc/dist/mac_frameworks/mac_e.htm should do. The Mac binaries have been built using gcc version 4.0.1 (Apple Computer, Inc. build 5367) and a patched Linker.lhs from http://hackage.haskell.org/trac/ghc/ticket/1798 (also the files compiler/main/DriverPipeline.hs and utils/hsc2hs/Main.hs are patched according to http://hackage.haskell.org/trac/ghc/ticket/1395) The PPC binary still features: http://hackage.haskell.org/trac/ghc/ticket/1845 The PPC ghc can be used on Intel Macs with the additional options: -optc-arch -optcppc -opta-arch -optappc -optl-arch -optlppc (but that's slower than an i386 binary). The Intel-Mac binary has also a patched file rts/Exception.cmm for http://hackage.haskell.org/trac/ghc/ticket/1980 (although I don't know if it is a Mac problem at all.) The Solaris 10 binaries have been built using gcc-4.2.2 http://www.dfki.de/sks/hets/pc-solaris/versions/ghc-6.8.2-i386-unknown-solar... http://www.dfki.de/sks/hets/solaris/versions/ghc-6.8.2-sparc-sun-solaris2.ta... The sparc binary was built on a "sun4u sparc SUNW,Sun-Fire-280R" using: SRC_HC_OPTS += -optc-mcpu=ultrasparc -opta-mcpu=ultrasparc Maybe these binary-dists are somehow useful. Christian
